We report the first observation of dijet events with a double Pomeron excha
nge topology produced in (p) over barp, collisions at roots = 1800 GeV. The
events are characterized by a leading antiproton, two jets in the central
pseudorapidity region, and a large rapidity gap on the outgoing proton side
. We present results on jet kinematics and production rates, compare them w
ith corresponding results from single diffractive and inclusive dijet produ
ction, and test factorization.
